Limestone is mainly constituent of chemical compound calcium carbonate (CaCo3). It is basically called sedimentary rock substance. As per researchers it forms 10% of total volume of Sedimentary rock. The extrusion & Implementation of limestone in any form deals with ease of work and as a less pollutant for Environment, hence it can be massively used and utilized as a replacement to coarse aggre...

This document is to serve as background technical information for engineers, specifiers, and other concrete technologists on use of limestone in hydraulic cements in amounts up to 15% (focusing on amounts between 5% and 15%). The document also provides supporting data for standardization of limestone blended cements in ASTM C595 and AASHTO M240. Environmental benefits are noted as well as a his...

Concrete's ability to auto-repair the cracks reduces need for maintenance and repair. Autogenous self-healing is an intrinsic property of concrete highly dependent on binder composition. The urgent necessity decrease CO2 emissions by replacing cement with “greener” materials provides challenges opportunities cementitious materials. This research aims verify behavior environmentally friendly mul...

Natural aggregates are gradually experiencing resource shortages and price accumulations with the rapid development rate of highway construction industry. Therefore, new materials social economic benefits must be identified to replace natural aggregates. Limestone was selected as representative aggregates, waste glass ceramics were chosen representatives solid in this article. This undertaken c...

Over the last few years the Texas Department of Transportation has expressed concern about mineralogical segregation (variation) of coarse aggregates used in bituminous mixes; problems are associated with variation in the quality of aggregates taken from a quarry/gravel pit. The primary objective of this project was to examine the effects of poor quality coarse limestone aggregate on hotmix asp...
